WATER-WHEEL.

Specification of Letters Patent.

Patented Nov. 4, 1919.

Application filed April 4, 1919. I Serial No. 287,492.

To all whom it may concern:

Be it known that I, CHARLES Ln Duo, a citizen of the United States,residing at Vernal, in the county of Uintah, Stateof Utah, have inventedcertain new and useful Improvements in WVater- VVheels; and I do powerfrom the amount of water consumed.

Another object is to provide a novel and improved device of thischaracter wherein friction is reduced to .a minimum'and the motor drivenat a comparatively slow but constant-speed and capable of developinggreat power. Other objects and advantages will be apparent from thefollowing description when taken in connection with the accompanyingdrawings:

In the drawings:

Figure 1 is a side elevation of a motor made in accordance with myinvention.

Fig. 2 is an edge View thereof.

Fig. 3 is a vertical sectional view taken on the line 33 of Fig. 2.

Fig. 4: is a horizontal sectional view taken on the line 4-4 of Fig. 1.

Fig. 5 is an enlarged vertical sectional view taken on the line 55 ofFig. 1, showing the arrangement of the lug 30 and pin 29.

Referring particularly to the accompanying drawings, 11 represents abase on which is formed the upwardly extending casing 10. This casinghas the side walls 10 which define a curved channel 16 for the waterwheel which will later be described. Also formed on the base are theupwardly extending supports 12, and mounted on the upper end of each ofthe supports is an L-shaped member 29 having a screw 30 in the verticalportion thereof. A bearing block 13 is disposed on the horizontalportion of the member 29 and has a slot ed ex-.

tension 31 through which a retaining bolt 32 is disposed and engaged inthe said horizontal portion of the member 29. The inner end of the screw30 bears against the adjacent side of the bearing block 13 whereby thesaid block can be slidably adjusted on the member 29. Journaled at itsends in the bearing blocks 13 is the shaft or axle 14: which carries thewater wheel 21. This wheel has the parallel peripheral flanges 2st whichengage in the channel 16 of the casing. In the periphery of the body 21of the wheel there are formed the recesses 23, and pivotally mounted ineach of said recesses is the blade 26. The shaft 27 of each blade isturned at right angles to the shaft, at one end, 'as shown at 27, whilethe other end is turned at right angles to the shaft but in a plane atright angles to the end 27. In the peripheral face of the body 21 of thewheel, and at one side of the recess, there is formed a groove 28 forthe reception of one end of the blade, so that the blade, whenfeathered, will lie flush with the peripheral face of the body. Formedon the casing, and opposite the grooved portion thereof,is a curvedguide 33, which is disposed in concentric relation to the shaft 14:, andin which is formed a channel or groove 3% for the reception of the ends28 of the shafts 27. On the upper end of the casing, and depending fromone side thereof, is a lug 30 which carries a horizontally disposed pin29, against which the ends 27 of the shafts 27 engage, successively, asthe wheel rotates, and by means of which the blades are turned to extendinto the groove 16 and receive the flow of water thereagainst. A waterconduit 17 is connected to the upper side of the casing 10, and has theoutlet opening 18 which registers with the opening 19 of the casing. Agate 20 is mounted in the conduit for controlling the flow of watertherethrough. The upper end of the channel 16 closed by the wall 25, sothat the water which issues from the conduit will be directed against.the blades of the wheel.

It will be noted that the lower end of the channel 16 is open to readilypermit the free discharge of the water which has passed through saidgroove and driven the wheel around. The portion of the casing oppositethat in which the channel 16 is formed, is open, so that there is nofrictional contact between the wheel and that side of the casing. Thusthe wheel only frictionally contacts with one side of the casing,thereby reducing the friction by one-half.

It will thus be seen that when the water is permitted to flow from theconduit lnto the casing, it will engage against the blade.

which is extended out into the channel'16. The force of the water willcause the wheel to rotate, as will be seen. As the wheel r0- tatcs theends 28 will engage in the guide 33 whereby the blades will be turnedinto their inoperative positions within the grooves 28'. As the ends 27successively engage with the pin 29 the blades will be turned to extendinto the channel 16 of the casing in position to receive the stream ofwater thereagainst. The blades are so disposed around the wheel that twoof them are under pressure of the water at the same time, while theremaining blades are in their inoperative position against theperipheral face'ofthe body of the wheel.

Thus, by reason of the fact that there is used a casing which ispractically one-half of the size of devices heretofore, a great economyof material is practised, the cost being greatly reduced, and frictionreduced to a minimum. i

What is claimed is: 1. A water motor including a segmental casing havinga channel therein, a flanged rotor movable within the said channel,

swingable blades carried by the rotor, means i on one side of the casingfor engagement pivotally mounted in each recess and having one endmovable into and out of said recess,

the other end of the blade being movable into and out of position acrossthe casing, the ends of the pivotal portion of the blades being extendedat right angles to the pivot and at right angles to each other, theeasing being, formed at one side with curved channel for engagementtherein of the ends of the said pivots, to turn the blades intooperative position, and a projection on the other side of the casing forengagement by and movement of the other ends of the said 7 pivots toturn the blades into inoperative position. v V In testimony whereof, Iaffix my signature, in the presence of two witnesses.
